My co-worker wrote an app in Java, which I call as a library within my own
app. His code is expecting an ArrayList, and up until now I've been handing
in an empty one like this:
accounts (java.util.ArrayList. 1000)
sentence-parse-response-map (.init instance-of-sentence-parser
incoming-message accounts contacts required-fields)
In my own code, I fetch the accounts and store it in a Clojure vector.
Imagine something like:
["Lisa Hare" "Morgan Aung" "Ki Xi"]
If I do this:
(ancestors (type accounts))
I see this:
#{clojure.lang.IPersistentStack java.lang.Comparable java.lang.Iterable
clojure.lang.IMeta clojure.lang.IReduceInit clojure.lang.AFn
clojure.lang.Associative clojure.lang.IReduce clojure.lang.ILookup
clojure.lang.IHashEq clojure.lang.Counted java.util.Collection
clojure.lang.Reversible clojure.lang.IEditableCollection
clojure.lang.Seqable java.io.Serializable java.lang.Runnable
clojure.lang.IPersistentVector java.util.concurrent.Callable
clojure.lang.IObj java.util.RandomAccess clojure.lang.Indexed
clojure.lang.Sequential java.util.List java.lang.Object clojure.lang.IFn
clojure.lang.IPersistentCollection clojure.lang.APersistentVector}
This:
(ancestors java.util.ArrayList)
gives me:
#{java.lang.Iterable java.util.AbstractList java.util.Collection
java.util.AbstractCollection java.io.Serializable java.util.RandomAccess
java.util.List java.lang.Object java.lang.Cloneable}
So what is the shortest path (of casts) to go from what I have to what he
expects? Should I cast to java.util.List and then call .toArray()?
